Learning objectives

In this topic, you’ll take a closer look at soil as a dynamic system composed of minerals, organic matter, living organisms, water, and air. You will explore how these elements interact to create soil, and how this hidden structure supports soil ecosystem services, influences plant growth, water movement, and other processes.

Through reflection and simple do-it-yourself (DIY) soil tests, you will observe soil from a scientist’s perspective - seeing it not just as the material beneath your feet, but as a living and vulnerable natural body full of activity and connections.

Learning objectives

After completing this topic, you will be able to:

• Define the main components of soil and describe their basic roles in soil functioning.

• Identify the texture of a soil sample using the feel (hand-texturing) method.

• Name examples of soil tests that can be carried out at home.
